Strange egg shaped mass growing on zoas

Just noticed it today. It seems to be eggs, but there’s nothing in my tank that’s pregnant that lays eggs like this. I have emerald crabs that I don’t think are pregnant and i have one cleaner shrimp that is pregnant but still carrying eggs.

Thanks!
Should we place it elsewhere in the tank
Or get rid of it?

We picked it off.
It was really firmly attached in between the polyps.

Nice, if you let it grow it would eventually choke out the coral
